OpenCV4Android - OpenCV DevZone. AndroidDependencies - Gnash Project Wiki. From Gnash Project Wiki Gnash unfortunately has many dependencies, most of which aren't 100% setup for cross compiling. These build notes depend on the most recent version of my Android C++ toolchain. I've got a lot of experience at cross configuring and cross compiling, so unfortunately, I did this the brute force way, rather than fix all the bugs in all the packages. There is also an order one needs to follow when building up all the dependencies from scratch.These package notes are in the proper order. The standard set of build options for everything is -fexceptions -frtti. the older -mandroid option is enabled in GCC by default now when you configure using arm-linux-androideabi as the host.
Javacpp - The missing bridge between Java and native C++
Introduction JavaCPP provides efficient access to native C++ inside Java, not unlike the way some C/C++ compilers interact with assembly language.

No need to invent new languages such as with SWIG, SIP, C++/CLI, Cython, or RPython as required by cppyy. Instead, it exploits the syntactic and semantic similarities between Java and C++.
